OIL-CAN.

Specification of Letters Patent.

Patented Dec. 12, 19l6.

Application filed May 7, 1915. Serial No. 26,584.

a To all whom it may concern:

Be it known that we, OLE FAULsoN and Jason B. NELSON, citizens of theUnited States, residing at Rhame, in the county of Bowman and State ofNorth Dakota, have invented new and useful Improvements in Oil-Cans, ofwhich the following is a specification.

The invention relates to oil cans, and more particularly to the class ofmachine oilers.

The primary object of the invention is the provision of an oiler of thischaracter wherein the parts thereof are readily and easily removed sothat in event the said oiler fails to work the same can be convenientlyrepaired.

Another object of the invention is the provision of an oiler ofthis'character wherein the pump for forcing the oil through the spout can beremoved so that the oil will freely flow through said spout, this beingdone should the pump become inoperative.

A further object of the invention is the provision of an oiler of-thischaracter wherein the construction thereof is of novel form to assurethe perfect working of the same.

A still further object of the invention is the provision of an oiler ofthis character which is simple in'construction, reliable and efficientin operation, and inexpensive in manufacture.

With these and other ojects in view, the invention consists in theconstruction, combination and arrangement of parts as will behereinafter fully described, illustrated in the accompanying drawing,and pointed out in the claims hereunto appended.

ln the drawings :Figure 1. is a side elevation of an oiler constructedin accordance with the invention. Fig. 2 is a vertical longitudinalsectional view thereof. Fig. 3 is a sectional view on the line 33 ofFig. 2. Fig. 4 is a St ctional view on the line 44lof Fig. 2.

Similar reference characters indicate corresponding parts throughout theseveral views in the drawings.

Referring to the, drawings in detail, the oiler comprises a body 5preferably made from metal, and is formed with an inwardly dished bottom6 and an upwardly arched or semi-sphericalshaped top 7 while'without thebody is a handle 8, the top 7 being formed with a central internallythreaded being formed with passages 15 adapted to register with thepassages 11 in the plug 10 so that oil from the body 5 will flowtherethrough to the spout for lubricating machinery or the like.

Mounted centrally in the inner plug 10 is a feed tube 16 which extendswithin the body 5 for a portion of the length of the same. Formed in thedished bot-tom centrally thereof is an internally threaded nipple 17 inwhich is detachably engaged a screw cap or plug 18, the nipple 17 beingformed with an inturned annular flange 19 at its inner end, andinsertible through this nipple 17 is a piston barrel 20, one end ofwhich is formed with an out-turned annular flange 21 to engage theflange 19 on the nipple 17, while its opposite end telescopes over theinner end of a hollow boss 22 which projects through the top 7 of thebody 5 and carries at its outer end a threaded cap 23 through whichworks the stem 2% of a piston 25 which is reciprocatingly movable withinthe barrel 20, and against this piston works a coiled expansion spring26 which is confined and held suitably seated within the said barrel 20,the spring being designed to automatically move the piston outwardlyafter being forced inwardly in the barrel,

.the outer end of the piston stem 24 being 28 and the flangedend 21oft-he said barrel.

On actuating the piston 25 within the barrel the oil contained thereinis under pressure for the feeding of the same to the feed tube 16 whichhas its inner end extended into the said barrel 20 for communicationtherewith.

The inner end of the barrel 20 is closed through the medium of aflexible disk 31 which'is seated upon the flange 2 1 and held fast bythe plug 18 when engaged in the nipple 17 in the bottom 6 of the body ofthe oiler. In the use of the pump the oil will be forced under pressurefrom the body 5 through the spout l-l for lubricating inachinery or thelike.

-The pump structure can be readily removed from the body 5 so that theoiler can be used in the ordinary well-known manner.

Detachably mounted in the top 7 of the body 5 is a cap 32 so that thesaid body can end of said tube 16, the valve being normally engaged inthe seat when the oil can is at rest so as to close the feed tube fromadmitting atmospheric air to the can.

From the foregoing description, taken in connection with theaccompaiu'mg draw-' ings, the construction and manner of operation ofthe device will be clearly understood, and therefore a more extendedexplanation has been omitted.

\Vhat is claimed is 1. An oiler of the class described comprising a bodyhaving a hollow boss formed at its top and also having a dished bottomprovided with a central internally threaded nipple, a barrel extendedthrough the nippie in the bottom and engaged with the boss at the top ofthe body, an annular flange formed on th lower end of the barrel andreceived in the nipple on the bottom, aclosure plug tapped in the nipplein the bottom and engaging the flange on the barrel, a plunger workingin the barrel, :1 spring seated within the barrel and acting upon theplunger, a two-part plug, one partbeing vided with a central internallydetachably mounted in the top of the body centrally thereof, a collardetachably connecting the two parts of the plug, a discharge spoutcarried by one part of the plug and a valved feed tube leading from thebarrel to the two-part plug, said two-part plug being formed withpassages for establishing communication between the body and the saidspout.

2. An oiler of the class described comprising a body having a hollowboss formed at its top and also having a dished bottom prothreadednipple, a barrel extended through the nipple in the bottom and engagedwith the boss at the top of the body, an annular flange formed on thelower end of the barrel and received in the nipple on the bottom, aclosure plug tapped in the nipple in the bottom and engaging the flangeon the barrel, a plunger working in the barrel, a spring seated withinthe barrel and acting upon the plunger, a two-part plug, one part beingdetachably mounted in the top of the body centrally thereof, a collardetachably connecting the two parts of the plug, a discharge spoutcarried by one part of the plug, a valved feed tube leading from thebarrel to the two-part plug, said two-part plug being formed withpassages for establishing communication between the body and the saidspout, a downwardly tapered valve seat formed in the barrel near thelower end thereof, said barrel being formed with a plurality ofapertures below said valve seat,

and a valve normally engaged in said seat.

In testimony whereof we afiix our signatures in presence of twowitnesses.
